Mod Mode Forged Carbon Case Set – 100m Diver with Lumed Bezel

The ultimate foundation for a stealth carbon build. After extensive R&D and a rigorous QC process, Mod Mode Watches engineered a case that delivers the lightweight, marbled aesthetic of forged carbon — without compromising on the structural reliability of stainless steel. The result: a 100m-rated diver that looks like nothing else on the modding market.

Why Forged Carbon?

Forged carbon isn’t just a material — it’s a statement. Unlike woven carbon fibre sheets, forged carbon is compressed under high pressure, creating an organic, marbled pattern that is completely unique to each case. The result is a case that is:

• Lighter than steel — without sacrificing rigidity

• One-of-a-kind — your build will never look like anyone else’s

• Visually striking — the marbled weave catches light in a way no metal can replicate

Hybrid Engineering: Carbon Looks, Steel Strength

The biggest weakness of carbon watch cases is thread integrity. We solved it. A precision-engineered solid steel inner cage reinforces every critical stress point — the screw-down crown and case back thread steel-to-steel, not carbon-to-steel. The result:

• ✅ 10ATM (100m) water resistance 

• ✅ Screw-down crown 

• ✅ Long-term durability — no thread stripping over years of case back openings

Lumed Bezel: Built for Low-Light Legibility

The fixed forged carbon bezel features integrated lumed markers — purpose-built for low-light readability. The carbon-on-carbon aesthetic keeps the stealth look intact while the lume ensures you can always read the time, day or night.

Frequently Asked Questions

Is forged carbon durable enough for daily wear?
Yes. Forged carbon is used in aerospace and motorsport applications. Our steel inner cage further reinforces all critical stress points, making this case suitable for daily wear and water activities up to 100m.

Will my case look exactly like the photos?
No — and that’s the point. Every forged carbon case has a unique marbled pattern. Your case will be one-of-a-kind.

Which movements fit this case?
NH34, NH35, NH36, NH37, NH38, NH39, NH70, NH71, NH72, 4R35, 4R36, 6R15, and 6R35. If you’re unsure, feel free to contact us before ordering.

What’s the difference between this and the Milsub Carbon Case Set?
This case features a fixed lumed bezel and a slightly smaller 40mm diameter — ideal for a cleaner, more understated diver profile. The Milsub version is 42mm with a rotating bezel, better suited for a classic dive watch aesthetic.

How many units are available?
Production runs are limited by the nature of forged carbon manufacturing. Once a batch sells out, restocking timelines vary. If you’re considering it, don’t wait.
